Pretty easy to see not too many guys here do any real tapping and threading
Vermont - used to be good but has gone the way of the Dodo and out sourced to China or India and has some pretty brittle taps. Not much good except for soft allows
Hanson is a bit better as they have been annealed properly and won't break off in the hole, but you won't get a lot of life out of them. You can watch them twist, but they start twisting pretty soon as the edge has worn off
Erwin - Never was any good that I know of and is bottom feeder stuff - wouldn't touch it under any condition
As for Snap On, Craftsman - don't have too much experience with them other then a few times with Craftsman. Don't remember what I was cutting - so no comment.
IF YOU CAN FIND THEN - and a Night and Day difference from the sets listed above
The Best Taps and Dies by far are Moorse, Butterfield, Greenfield even pre-1980s Vermont-American for the older stuff but there is still some NOS out there. Titain, OSG for the newer stuff.
Keep some Half Round polishing stones in your set and de-burr / clean the flutes after use and your taps will last for decades
Nothing worse then a tap broke off in a hard to replace / impossible to replace part that is a must have.
